在细菌细胞中,组氨酸激酶(HK)是监测环境和细胞内刺激的受体。HK及其同源反应调节因子构成了通过可逆蛋白磷酸化调节细胞稳态的双组分信号系统(TCS)。在这里,作者表明,植物病原体野油菜黄单胞菌pv.油菜通过不可逆的蛋白水解修饰调节HK(VgrS)的活性来响应干旱胁迫条件。这种调节是介导的周质,PDZ结构域含有蛋白酶(Prc),切割的N-末端传感器区域的VgrS。VgrS的切割抑制其自身激酶活性,并调节同源反应调节因子(VgrR)结合下游基因启动子的能力,从而促进细菌对细菌胁迫的适应。
In bacterial cells, histidine kinases (HKs) are receptors that monitor environmental and intracellular stimuli. HKs and their cognate response regulators constitute two-component signalling systems (TCSs) that modulate cellular homeostasis through reversible protein phosphorylation. Here the authors show that the plant pathogen Xanthomonas campestris pv. campestris responds to osmostress conditions by regulating the activity of a HK (VgrS) via irreversible, proteolytic modification. This regulation is mediated by a periplasmic, PDZ-domain-containing protease (Prc) that cleaves the N-terminal sensor region of VgrS. Cleavage of VgrS inhibits its autokinase activity and regulates the ability of the cognate response regulator (VgrR) to bind promoters of downstream genes, thus promoting bacterial adaptation to osmostress.
